摘　　要：针对宽频带电子信号侦测系统测向精度与解相位模糊能力这一矛盾问题,根据多基线测向原理,提出一种基于宽频带多基线阵列解模糊的波达角估计算法,并进行了仿真分析。结果表明,该方法可有效求解宽频带多基线阵列相位模糊,提高对目标在相位差测量精度不高情况下的测向精度。In view of the contradiction between direction-finding accuracy and phase ambiguity resolution capability for the wideband electronic signal detection system,according to the principle of multi-baseline direction finding,a direction of arrival(DOA)estimation algorithm is proposed based on the wideband multi-baseline array ambiguity resolution,and simulation analysis is carried out.The results show that the method can effectively resolve the wideband multi-baseline array phase ambiguity and improve the direction-finding accuracy of the targets with low phase difference measuring accuracy.
